machinery'7 and it is undesirable itnot imi practicable to print the exterior of the bags l have Jfound in working out my of making filled bags from continuous' rolls of material, that it is highlyv inconvenient owing to various conditions and business methods which prevail in this art, to print the bag material as part of the inunediate process ot' making and filling the bags. l.

tind that it is better to do the bag printing as a separate process and to feed from continuous rolls ot' such separately printed bag material into the apparatus lor making and filling such bags.

It is, howe\'er, indispensablel `that the printed material on cach bag should he properly located on the' nnished bag, otherwise the 4finished product will be unsymmetrical. -lt is extremely rlillicult, owing to the use of machines and the necessity of relying on those who operate the-machines,"

n comes into proper position on the outside Two seams are then run to get this necessary symmetry.

For all these reasons` l have worked out' the solution of the problem.'

Theinvention is illustrated in the aecompanying drawing whereinl Figure l1 is a diagrammatic representation of a method of forming the printed roll; Fig. 2 is a plan View of a section of such printed roll; Fig: 3 is a view of a filled bag formed l'rom such roll.

Like parts are indicated by like letters throughout the several gures.

A is a roll'ot raw or imprinted material; B a printing apparatus, diagrammatically shown. through which itpasses, and C a. roll of the finished or printed material. Dy is the material in question which is shown with lli successively printed and similar section l, lil at the side and the intermeing and the severing a're to bedone.

-diate indication marks F, which indicate the line of severance. (i, Gr are the stitching line indicator marksplaced on' opposite sides` of the lines F, F in equal distance therefrom. These. lines may be iliade in any desired manner, the object of them beingto clearly show -the operator Where the stitch- Une or more of them may beused.` The rolls of such: printd'marked material maybe prepared anywhere andl apart from or in a factory or building'other than that in which;

the bag filling and making operation is car-rv ried out. The rolls so formed', printed and marked, are fed--intopthe bag filling and making machine in any desired manner, and the product emerges as the finished bag With the printed lmaterial in every instance in the exact desired position on the bag.v

The operator has always before hin, .as the work progresses the I :uark or marks indicating where the' goods is to be stitched. or 'severed or both, 'so that the roll ywill alwys be placed, by him, in the proper position to iin-A.

sure the desired. symmetry. l The printed material, iii-actual practice, 1s first folded and stitched so asY to form al tube'with the seam outside andthe printed f matter inside. This tube is then reversed so series of measured quantities, each of which occupies a section of the tube, and the tube 1s so manipulated that the printed material of such tube. across the tube, between successive charges,

'. and the bag material is severed between the seams, and by continuing this process a series of bags will be produced from this matcrial. tion is made certain by the presence of the indicating lines or marks, so as always to bring the printed material 'into symmetrical relation withvthe e'nds of the bag.

vI have spoken' of the roll of material but, of course,'it will be. understood that by that term l mean to indicate any strip of-material of any length or size or shape, roll or otherwise. I claim This stitching and severing opera 1. As anew article of manufacture, a roll v of bag material adapted to be folded, seWed and severed to form separate bags, said bag" material being provided With transverse indicating'markings for the direction of the operator in forming it into a seriesV of uniform bags, and with a seriesof uniform '1m pressions containing matter appropriate to such proposed bags land rarranged substantially inl the middle of.each successive area` Vindicating markings for the direction of the operator in forming it into a series of uniform bags, and with a series of uniform' impressions each containing matter' appropriate to one ofsuch proposed bags and arranged substantl'a-lly in the middle of each successivey area bounded by the indicating -markings, a longitudinal edge, and the central longitudinal line of the roll.

As a new article o manufacture, a strlp of bag material of proper width to have its edges'un'ted and form'a bag "tube and long enoughfsorthat thetube so formed may be divided in toma plurality of bags, said strip being provided with' a series of indi-' eating markings, properllocated to guide anoperator in sewing an severing the tube transversely to form separate'bags, and with a series 'of impressions,l each 4impression of the series containing matter' appropriate to 1a separate bag so formed, and each located substantially in the middle of an .rea

bounded by a longitudinal edge of the strip,

'the central vlongitudinal line of the strip,

Vand two of t-he lines of severance indicated by said indicating markings.

In testimony whereof I have hereunto signed my name to this specification.
